java读取PHP接口数据的实现方法
和安卓是一个道理,读取json数据
php文件:
class Test{
//日志路径
const LOG_PATH="E:\phpServer\Apache\logs\\error.log";
//显示的行数
const PAGES=50;
public static function main(){
header("content-type:text/html;charset=utf-8");
if(!empty($_GET['action'])){
if(!method_exists('Test',$_GET['action'])){
echo "404";
}else{
self::$_GET['action']();
}
exit;
}
}
public static function showApacheLogs(http://){
$test=new Test();
$result=$test->readLogs(self::LOG_PATH,self::PAGES);
$json=array();
for($i=0;$i $line=$result[$i]; //注意这里,如果处理会json解析失败 $line=str_replace("\r\n", "", $line); $result[$i]=array("num"=>$i+1,"msg"=>urlencode($line)); } $str=stripslashes(urldecode(json_encode($result))); http://echo $str; } /** * 读取日志 */ private function readLogs($filePath,$num=20){ $fp = fopen($filePath,"r"); $pos = -2; $eof = ""; $head = wVljknkqfalse; //当总行数小于Num时,判断是否到第一行了 $lines = array(); while($num>0){ while($eof != "\n"){ if(fseek($fp, $pos, SEEK_END)==0){ //fseek成功返回0,失败返回-1 $eof = fgetc($fp); $pos--; }else{ //当到达第一行,行首时,设置$pos失败 fseek($fp,0,SEEK_SET); $head = true; //到达文件头部,开关打开 break; } } array_unshift($lines,fgets($fp)); if($head){ break; } //这一句,只能放上一句后,因为到文件头后,把第一行读取出来再跳出整个循环 $eof = ""; $num--; } fclose($fp); return array_reverse($lines); } } Test::main(); java文件: import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; import org.json.JSONArray; import org.json.JSONObject; public class ReadLogs { public static void main(String[] args) throws Exception { URL url = new URL("http://localhost/test.php?action=showApacheLogs"); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setConnectTimeout(10000); conn.setRequestMethod("GET"); conn.setDoInput(true); conn.setDoOutput(true); // 输出返回结果 InputStream input = conn.getInputStream(); int resLen =0; byte[] res = new byte[1024]; StringBuilder sb=new StringBuilder(); while((resLen=input.read(res))!=-1){ sb.append(new String(res, 0, resLen)); } String jsonStr=sb.toString(); //String转换成JSON JSONArray jsonArray=new JSONArray(jsonStr); for(int i=0;i JSONObject jsonObject=new JSONObject(jsonArray.getString(i)); String msg=(String) jsonObject.get("msg"); int num=(int) jsonObject.get("num"); System.out.println(num+":"+msg); } } }

$str=stripslashes(urldecode(json_encode($result)));
http://echo $str;

/**
